An Ultimate Powerbox v2 and Pocket Powerbox Advance expansion accessory

The external motor controller (XMC) was designed to expand the focus capabilities of the Ultimate Powerbox v2 (supports a 2nd focus controller) and adds focus functionality to the Pocket Powerbox Advance. The device does not require a USB cable and can be attached directly to the EXT port of the Powerboxes. It can drive a large bipolar or unipolar stepper motor (up to 2Amps per coil) with high precision.

Controller support micro-stepping which can be configured via software to Full, Half, 1/4 step and 1/8 step. This provides additional precision and a smooth rotation from the stepper motor.

Supported Motors
We have successfully tested and controlled the following stepper motors:



Pegasus Motor Focus (v1 & v2) Straight RJ45 Network Cable
Starlight HSM 25 / 30 / 35 PEG-CMOT-HSM
Starlight MSM 25 / 30 / 35 PEG-CMOT-MSM

Moonlite Stepper Motor PEG-CMOT-RJ45DB9
Robofocus Stepper Motor PEG-CMOT-RJ45DB9

Lacerta Motor PEG-CMOT-LCRT

Please note that each motor requires its own cable due to different pin-out selection of each manufacturer. * We optionally provide any of these cables. Check cable type SKU at below table.

No USB port is required
You do not have to occupy a USB port as the controller does not require a USB connectivity. Just plug the RJ12 port into the EXT port and the controller will be recognized from the powerbox software. Simple as that!

Second EXT port available
A second EXT port allows you to daisy chain future equipment or connect your environmental sensor.

The controller is fully protected against undervoltage, overcurrent, and overtemperature events.
